Review: It works!!!! - I’ve tried everything killing weeds on my lawn , finally I found this herbicide works wonders all weeds gone . Outstanding product. Review: Doesn’t work at all. Absolutely no change what so ever. - Mixed up the herbicide per the instructions on the container to get rid of my crabgrass. Two weeks later the grass is as green and thriving as ever. No change at all. So I’m going to try again, doubling the amount of herbicide to water. Will see if that does anything. ## Features - Targeted Control: Effectively handles crabgrass, especially during its 3-5 tiller stage. - Enhanced Efficiency: Uses a unique formula for improved performance and enhanced rainfast in 2 hours. - Versatile Use: Suitable for various lawn types. - Barnyardgrass (Echinochloa crusgalli) Large crabgrass (Digitaria sanguinalis) Smooth crabgrass (Digitaria ischaemum) Giant foxtail (Setaria faberi) Green foxtail (Setaria viridis) Yellow foxtail (Setaria pumila) Kikuyugrass (Pennisetum clandestinum) Broadleaf signalgrass (Brachiaria platyphylla) Torpedograss (Panicum repens) - Lawn Types: Bermuda, Zoysia, Ryegrass, Kentucky bluegrass - Special Features: Contains H-value which increases absorption efficacy - Application Rate: 1.10-1.45 fl.oz. per 1,000 sq. ft ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D7TNLT16 | | Best Sellers Rank | #222,297 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #684 in Weed Killers | | Brand | Lawn Synergy | | Brand Name | Lawn Synergy | | Coverage | 44,000 sqft - 58,000 sqft | | Customer Reviews | 3.6 out of 5 stars 5 Reviews | | Included Components | Jug | | Item Form | Liquid | | Item Weight | 5.1 Pounds | | Liquid Volume | 64 Fluid Ounces | | Manufacturer | Prime Source | | Part Number | 2233 | | Unit Count | 64.0 Fluid Ounces | ## Product Details - **Brand:** Lawn Synergy - **Item Weight:** 5.1 Pounds - **Liquid Volume:** 64 Fluid Ounces - **Item Form:** Liquid - **Manufacturer:** Prime Source ## Images ![Quintessential Crabgrass Weed Killer - Kills Crabgrass Fast - 1/2 Gallon Treats 44,000 to 58,000 sqft. - Image 1](https://m.media-amazon.com/images/I/51blI3g-ugL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works!!!! *by E***A on September 28, 2025* I’ve tried everything killing weeds on my lawn , finally I found this herbicide works wonders all weeds gone .
